I need to make a 3D colliders in Unity with those forms. I don't want to use any Asset Store asset if it's possible. There are two models: both are cylinders but they have some deformations (see image below).
I need to make a collider of both cylinders but it needs to be accurate (I mean, the holes mustn't be in the collisions). As I said, I don't want to use any thing Asset Store if it's possible. So it have to ve with primitive shapes or with mesh colliders, that I can't get them to work propertly with my meshes.
